Yaz and Yasmin Birth Control Risky Due to Drospirenone
The U.S. Food and Drug Administration (FDA) has completed its review of
studies of the risk of blood clots in women taking birth control containing
dropsirenone. Drospirenone is a synthetic form of the female hormone,
progesterone, and is also known as a progestin. The study concludes that
birth control pills containing drospirenone may put users at a higher
risk of blood clots than other birth control pills that contain other
progestins. Drospirenone is found in Yaz, Yasmin and Ocella.
The study did not take known and unknown patient characteristic into account,
however. Some of the unaccounted characteristics could affect the patient's
blood clot risk. This results in an inconsistent estimate of what percentage
the risk of blood clot is while taking birth control, such as Yaz or Yasmin,
that contain drospirenone.
The FDA ordered revised drug labels for Yaz, Yasmin, Beyaz and Safyral
to now state that some studies report pills containing drospirenone have
as much as a three times greater risk of blood clots than pills containing
different types of progesterone, such as levonorgestrel. Other studies
have shown no correlation between drospirenone and blood clot risks.
"At this time, health-care professionals should consider the risks and benefits
of drospirenone-containing birth control pills and a woman's risk
for developing a blood clot before prescribing these drugs. Additionally,
adverse events involving drospirenone – containing products should
be reported to the FDA", states the FDA website.
